Need help identifying the aircraft Bell P-39 Airacobra

[maximus_des]

Good afternoon, my name is Maxim Vasilyevich, I am a member of the search group from Belarus. We are looking for dead soldiers of the Great Patriotic War on the territory of Belarus. We recently discovered the remains of a Soviet assembly that was shot down in 1944. The plane turned out to be a Bell P-39 Air Cobra. These aircraft were supplied to the USSR under Lend-Lease. After the plane crashed, an explosion was discovered and no large fragments remained from it. Recently, a plate from the radio station with a number was found. Perhaps you can somehow help in finding this recorded number?
A nameplate (tablet) from a radio station with a number was found. It is necessary to find out on which aircraft this radio station was installed. 4411-01
Sorry for my English.

The Hamilton Standard placard is probably from the propeller. The BC-451-A placard is from a radio control box

would a prop had a plate bolted to it? Looks like metal but cant be.

sometimes they used a thin metallic plate held on with adhesive

As memo serves the soviet Airacobras had either the Curtiss Electrics or the Aeroproducts propellers. So the Hamilton Standard ID card might be from another device or the plane wouldn't be the P-39.

Yes, you are correct! Maybe the prop governor?

 

[Wurger]

Yep .. that's very possible.

 

[Wurger]

Here is the one for the Stearman for instance. The ID card is similar as the number of the device.

[Snautzer01]

That looks more a possibility.

 

[FLYBOYJ]

Yep! And looking at those placards carefully, they are held on by rivets which would seem very unlikely on a prop blade!

 

[Wurger]

I agree. the number there seems to be the 4K11-G1. So the device could be the Hamilton Standard Propeller Governor Model 4K11-G1*.

And another HS governor ...

FLYBOYJ Thats what thought in my first post on the subject, know too little about props.
Wurger well done !

A note though .. the governor model could be the 4K11-G1J. The last letter of the model seems to be unreadable in the placard. But the "J" is very likely as the number for the device model I found in the "List of Propellers and Governors for Service Aircraft 1945". Unfortunately it is assigned to the A-20.
The Lockheed B-34 and B-37 used 4K11-G1E. A quite similar model IMHO. B-25A/B used the 4L11-G1J. The governors for the P-39 had the different numbers for its model. However these models for the P-39 series seem to be for the Curtiss props but there is nothing about the Aeroproduct ones. So ...

So maybe it's not an P- 39 aerocobra?

Here is another photo of small parts with numbers:

another plane plaque found

 

[maximus_des]

a stamp and a plate were found

 

[Wurger]

The plate looks like being from a suction relief valve B-12 used for many aircraft with the Pratt & Whitney engines. The part indicates a radial engine rather than the inline unit used for a P-39.

Could this be on the A-20 Boston?

 

[Wurger]

Yes, that's very possible.
